Abstract (en)
[origin: WO8502481A1] Disk-shaped recording medium on which are recorded a first data signal, such as digital audio data, a second data signal in the direction of reproduction and of the disk, such as digital video data and computer program data, and identification data recorded in the read-in track for representing the fact that the second data signal has been recorded. It is possible for this recording medium to be reproduced by a reproducing apparatus which is exclusively used for a conventional disk-shaped recording medium on which the first data signal alone has been recorded. Also disclosed is an apparatus for reproducing the above-described disk-shaped recording medium. The apparatus includes: a circuit for processing the reproduction of the first data signal; a circuit for processing the reproduction of the second data signal; and a control circuit which is supplied with reproduction control data for discriminating between a conventional disk-shaped recording medium on which the first data signal alone has been recorded and a disk-shaped recording medium on which both the first and second data signals have been recorded. By the output of the control circuit, the control of the reproducing operation of a pickup is changed over, and the circuits for processing the reproduction of the first and second data signals are also changed over from one to the other.
